Should We Attend More or Less? Modulating Attention for Fairness

no code implementations22 May 2023 Abdelrahman Zayed, Goncalo Mordido, Samira Shabanian, Sarath Chandar

In this work, we investigate the role of attention, a widely-used technique in current state-of-the-art NLP models, in the propagation of social biases.

Deep Learning on a Healthy Data Diet: Finding Important Examples for Fairness

1 code implementation20 Nov 2022 Abdelrahman Zayed, Prasanna Parthasarathi, Goncalo Mordido, Hamid Palangi, Samira Shabanian, Sarath Chandar

The fairness achieved by our method surpasses that of data augmentation on three text classification datasets, using no more than half of the examples in the augmented dataset.

Fast Strain Estimation and Frame Selection in Ultrasound Elastography using Machine Learning

no code implementations16 Oct 2021 Abdelrahman Zayed, Hassan Rivaz

In the inference stage, we use dynamic programming (DP) to compute an initial displacement estimate of around 1% of the samples, and then decompose this sparse displacement into a linear combination of the 12 displacement modes.

Automatic Frame Selection using CNN in Ultrasound Elastography

no code implementations17 Feb 2020 Abdelrahman Zayed, Guy Cloutier, Hassan Rivaz

Ultrasound elastography is used to estimate the mechanical properties of the tissue by monitoring its response to an internal or external force.

Automatic Frame Selection Using MLP Neural Network in Ultrasound Elastography

no code implementations13 Nov 2019 Abdelrahman Zayed, Hassan Rivaz

This work focuses on strain imaging in quasi-static elastography, where the tissue undergoes slow deformations and strain images are estimated as a surrogate for elasticity modulus.

Fast Approximate Time-Delay Estimation in Ultrasound Elastography Using Principal Component Analysis

no code implementations13 Nov 2019 Abdelrahman Zayed, Hassan Rivaz

Time delay estimation (TDE) is a critical and challenging step in all ultrasound elastography methods.
